A for-loop is apart of a family known as control-flow; you can denote a form iteration built from a condition to define how the code will iterate through the instructions in it's scope. Alternatively, we can use iterator functions to define specific flows for specific scenarios.
A common iterator-function is the enumeration function. This will allow us to traverse through a list of elements in a form of key-value pairs, meaning we can attain an index (where the element in rotation is in the given table; subsequently, in a Dictionary we can attain a reference) and a value (what that element is)
The Index and Value are usually represented as i and v, but can be named anything we want.
local ArbitraryTable = {4, 6, 1, 4, 5}
for i, v in pairs(ArbitraryTable ) do
print(i, v)
end
--[[ Output:
Where in the table: Value of that element:
1 4
2 6
3 1
4 4
5 5
]]
